Dual Frequency Orbiter-Radar System for the Observation of Seas and Tides on Titan: Extraterrestrial Oceanography from Satellite [PDF]

open access: yesRemote Sensing, 2019
Saturn’s largest moon, Titan, is believed to have a ~100 km thick ice shell above a global ocean of liquid water. Organic materials, including liquid hydrocarbon lakes and seas in its polar terrain, cover Titan’s surface, which makes it a ...

Spaceborne Synthetic Aperture Radar for Oceanography

open access: yesIEEE Journal of Oceanic Engineering, 1982
The book originates from a symposium held at the Applied Physics Laboratory of the Johns Hopkins University in March 1980. The purpose of the symposium was to review the results to date of investigations related to the SEASAT SAR (synthetic aperture radar) experiment and, to quote from the book's foreword, ‘to explore the potential’ of such satellite ...

High Performance Simulation of Spaceborne Radar for Remote-Sensing Oceanography: Application to an Altimetry Scenario

open access: yes2024 International Radar Conference (RADAR)
In this paper, we detail the high-performance implementation of our spaceborne radar simulator for satellite oceanography. Our software simulates the sea surface and the signal to imitate, as far as possible, the measurement process, starting from its lowest level mechanisms.

Progress in Compact HF Radar Measurement of Bimodal Ocean Wave Parameters

open access: yesRemote Sensing, 2022
We describe an extension of methods used for the derivation of wave information from compact high frequency radar systems and give examples of observations which are compared to measurements from wave buoys close to the radar coverage area.

First Open-Coast HF Radar Observations of a 2-Phase Volcanic Tsunami, Tonga 2022

open access: yesRemote Sensing, 2023
We describe results from coastal radar systems that observed anomalous current flows generated by the volcanic eruption in the Tongan archipelago on 15 January 2022 UTC, reporting the first radar detection of a volcanic tsunami. The eruption caused small

Remote Sensing of the Polar Ice Zones with HF Radar

open access: yesRemote Sensing, 2021
Radars operating in the HF band are widely used for over-the-horizon remote sensing of ocean surface conditions, ionospheric studies and the monitoring of ship and aircraft traffic.

Comparisons of Tidal Currents in the Pearl River Estuary between High-Frequency Radar Data and Model Simulations

open access: yesApplied Sciences, 2022
High-frequency (HF) radar data, derived from a pair of newly developed radar stations in the Pearl River Estuary (PRE) of China, were validated through comparison with in situ surface buoys, ADCP measurements, and model simulations in this study.
